Pro Shaft Rocker Kit SBF 1.60/1.60 AFR

The JESEL Pro Shaft Rocker Kit SBF 1.60/1.60 AFR is a high-performance valve train solution designed for serious small-block Ford builders and performance enthusiasts. This kit is ideal for both naturally aspirated and forced-induction applications, providing a fully adjustable, low-friction rocker arm system that enhances valvetrain efficiency and reliability at high RPM.

Featuring a 1.60-to-1.60 rocker ratio, this kit offers equal mechanical advantage on both intake and exhaust sides, making it particularly suitable for AFR (Air Flow Research) cylinder heads and modern, high-lift camshaft profiles. The shaft-mounted design minimizes side-to-side rocker arm wear and deflection under load, while allowing for precise tuning of lash and geometry through adjustable pushrods and rocker stands.

This rocker kit is perfect for small-block Ford owners looking to maximize performance with aftermarket cylinder heads and aggressive camshaft profiles exceeding 0.500 inches lift. With a recommended RPM range exceeding 7,000, it is an essential component for street engines, road-race platforms, and competition powerplants.
